Abstract

A unified approach is introduced to compute the induced current density on the surface of conducting bodies of revolution by radiation from a circular loop antenna placed coaxially relative to these bodies. The theory of the circular loop antennas is applied to the loop part, while the numerical Method of Moments to the body. This technique divides the solution into two distinct independent parts. Partitioning the problem in such way, with using the EFIE formulation makes the procedure general, simple, and efficient in terms of computation time and storage. The procedure is applied for some bodies of revolutions including sphere, cone-sphere, circular disk and toroid. The results for the case of the disk which represent a finite ground plane problem are with good agreement with the available published results.
